APPARATUS FOR AND PRQCESS QF LINING CAN ENDS.

Application filed. May 16, 1921. Serial No. 470,081.

This invention relates in general to the lining of can ends and has more particular reference to the provision of ends lined with compound applied in liquid or semi-liquid form.

The invention has for its principal object the application of the gasket liner material directly to the flange of the can end in minutely accurate measured amount and in such, fashion as to insure its even distribution over the area designed to receive it.

The invention has for a further object the provision of an apparatus and process of lining can ends, which will permit the accurate and satisfactory lining of the ends with liner material thicker and less fluid than is readily practicable with the nozzle or jet apparatus now generaily in use and well known to those skilled in the art.

r-inother highly important object of the invention is the provision for accurately measuring the entire charge and for varying the amount of this charge as conditions may render desirable.

Another important object of the invention is the provision of an apparatus and process insuring against the delivery of liner material except when a can end is present to receive it.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawing,

Fig. 7 is a perspective view of one of the feeder disks.

The apparatus shown on the drawing for the purpose of illustrating the invention will be first described. Referring to Fig. 2, reference character 11 indicates the frame of the machine and reference characters 12 and 13 brackets that extend up from it. These brackets support a reservoir comprising a body 14 having wings 15 and 16 resting upon and secured to the brackets 12 and 13. The bottom of the reservoir consists of a plate 17 having an upwardly extending hollow sleeve 18 at its center which sleeve extends, through a reservoir top plate 19. \Vithin this sleeve is mounted a, pressure plunger 21 having a head 22 adapted to engage the body of a can end as will be presently described. The plunger is provided with a stem 23 extending through a vertically ad.- justable bushing 24 and normally pushed down by a spring 25 until a stop nut 26 en gages the top of the bushing. The head of the plunger is rotatably mounted upon the stem, having a shoulder 27 engaged by the head 28 held in place in the stem by a screw 29. Antifrictiou balls 31 are provided to peripit independent turning of the plunger war.

A can end support, consisting in the present instance of a seat member 32 upon the upper end of a. rod or stem 33, is arranged axially beneath the plunger head 22. A. spring 34 is provided upon th lower end of this rod 33 and normally presses the can end support to the frame 11. Beneath the frame is. mounted a cross-shaft 35 in bearings 36 and upon this cross-shaft is a cam 37 adapted in, the rotation of the shaft to lift the support and the can end carried by it into contact with the plunger head 22. Rotation is innparted to the can end by a bevel gear 38 mounted on shaft 35 and meshing with a bevel pinion 39 slidably embracing or keyed to the stem 33. The can ends to be lined are arranged in a magazine or stack holder defined by posts 41 extending up from a plate 42, which plate is supported at 43 on the lower part of the bracket 13. Beneath this plate is arranged a reciprocating slide 44 having rollers 46 at one side movable through a guide carried on the frame. This slide is provided with a can end receiving recess 47 terminating in can end cutout shoulders 48 at the rear end. The slide is reciprocate-d by a link 49 from any suitable power source, being so timed with respect to the can end support or lift that it will deliver a can end thereto each time it returns to normal position after being lifted by the cam 37.

(ill

The slide carries fingers 51 at its forward end for pushing the can end previously positioned i rom the support, and these lingers move back with the slide beneath the support after it has been raised, as may be readily perceived on viewing Fig. 1-.

The gasket material is fed to the rotating can ends in measured amounts, each charge in the present instance consisting of a number of measured drops or minute measured quantities. A number of disks 61, a sample or which is shown in Fig. 7, are provided. Each said disk is formed with several peripheral pockets 62. The plate or bottom 17 or the reservoir is given the general triangular shape shown in Fig. 5 and to each side or leg thereof a sector member 63 is fastened'by bolts G l. Each sector member has a circular recess 65 in which a disk 61 is arranged and lit-ted, and this disk is mounted upon a rotatable pin or shaft 66' to which it is lined against independent rotation by a tooth 67 engaging in the. shaft. The walls of this recess close and make individual pockets (32 of the disk. This shaft has bearing in a s eeve 68 in the sector and in bearing 69 in the plate 17. A bevel pinion 71 is pinned to the outer end of each shaft 66 and these pinions are adapted to engage with a bevel gear ring 72 when the parts are. assembled. This gear ring rests upon shoulders 73 upon the plate 17 and sectors 63, and'in turn is surrounded by a second or actuating ring 74 held in place by an annulus 75 resting on the top of the gear ring and secured to the actuating ring by screws 7 6.

Referring now to F i g. 8, it will be noted that clutch recesses 77 are provided in the periphery'ot the gear ring and in these recesses are arranged clutch rollers 78 adapted to cause the gear ring 72 to move with the actuating ring Tel when the actuating ring is moved in a counterclockwise direction, viewing Fig. 3. The actuating ring is provided with an arm 81 having an extension 82 connected by a link 83 with a slide 84 movable in guides 85 alongside the slide ed. The slide 84L is in turn actuated by pivot arm 86 pivoted at 87 to the back oi the slide 4% and having at its forward end a tooth 88 adapted for engagement in a recess 89 on the slide 8-1 when a can end is advanced by the slide The tooth 88 normally rests out of posit, Hi to engage the slide 84 and is moved into enga 7 n position by a projection 91 on a lever 92 mounted upon the table or frame beneath the slide 44:. This lever has a second projection 93 dapted to be engaged by the can end as it advanced by the slide 4% and as will be readily appreciated upon examination of Fig. 1. The tooth 88 has an inclined face 94 at its rear side adapted to be engaged by a lug 95:- on the slide return movement to move the tooth back to normal position after the liner applying operation.

The operation of the apparatus and the practice of the process of my present in vention will be readily apparent. The slide id is moved forward cutting out and advancing the lowermost can end from the magazine or stack between the posts 41. The presence of this can end moves the arm 86 down over into engagement with the slide 8% and further advance turns the actuating ring 74 on its idle stroke. As soon as the can end arrives on the support it is lifted into engagement with the plunger head 22 and against the disks 61 and at the same time is rotated by the gears 38 and 39. Upon the return stroke of the slide 44 the lug 88 engages the lug 95 of the slide 84 and moves the actuating ring in the opposite direction. This movement of the actuating ring produces like movement or the bevel gear ring 72 with corresponding rotation of the disks 61. These disks in rotating carry minute charges of liner material in the pockets 62, the material 96 between these pockets engaging curved end surtac-es o'i the recesses in the sector plates 63 and serving as cut-offs, so that only measured quantities of material will be delivered and only by rotation of the disks. The disks operating together simultaneously deposit series of small measured quantities of the liner material on the flange of the can end and the surfaces between the pockets, rolling on the flange, distribute this material. The measuring is peculiarly accurate because of the small amounts delivered and it will be apparent that the disks rotating in the liner material itself can discharge semi-liquid as well as liquid if de sired. The parts are preferably so arranged and timed that the material between pockets extends down to the can end flange and any excess rotation causes further spreading action. The amount deposited depends upon the arc of rotative movement given the gearing 72 and I provide means for varying this rotative movement. Upon the arm extension 82 a number of points of attachment for the link 88 are provided, as indicated at 97. The link may thus be connected at any or" these points of attachment and the angular throw correspondingly changed. I preferably also provide friction packing 98 between the. gear ring 72 and the reservoir wall. A pipe 99 let into the side of the reservoir wall may be provided if desired to supply the liner material to the reservoir.

It is thought that the invention and many of its attendant advantages will be understood troin the foregoing description, and it will be apparent that various changes may be made. in the lorn'i, construction and arrangement ot the parts without departing from the spirit and scope of the invention or sacrificing its material advantages, the
